Bug#847154: linux-image-amd64: Disabling vsyscall interface may break docker run
Package: linux-image-amd64
Version: 4.8+76
Severity: wishlist
Dear Maintainer,
You may want to add to the NEWS blurb that disabling the old 'virtual
syscall' interface can lead to crashes when trying to run a Docker
container. With upstream's docker-engine-1.12.3-0~stretch, I see
docker run -it --rm centos:6.8 /bin/bash
exit with a 139 status (and may leave a core file). Adding a
vsyscall=emulate
to the kernel parameters fixed this for me.
When using the centos:7 image, this problem does not occur.
On 4.7.0-1-amd64, both centos:6.8 and centos:7 Docker images work
without any problems.
Seeing that the centos:7 image works fine, I am inclined to think that
this problem may be limited to older Docker images. I have not done any
research to back this up, nor do I plan to.
